Title: Lateral transistor
Inventor: FUSHIMI IKUO
IPC: H01L29/06
Filed: 1985-02-12
Abstract: PURPOSE:To prevent the situation that unnecessary current flows to the substrate and ground sides, by providing a semiconductor region of reverse conductivity type at the collector region on the opposite side of the emitter region. CONSTITUTION:After an N<+> type buried layer 12 is formed on a P<-> substrate 11, an N<-> layer 13 is formed by epitaxial growth. Then, a P<+> region 14 is formed as the element isolation region by diffusion or the like, thus electrically isolating the N<-> layer 13 for every element. A P<+> emitter region 15, the first P<+> collector region 16, the second P<+> collector region 17, and a P<+> region 18 surrounding the collector regions 16 and 17 are formed; finally, an N<+> region 19 is formed so as to surround the P<+> region 18. When a voltage lower than that to the collector region C1 or C2 is made to be impressed on the electrode T, even if a transistor comes into saturated action by the reduction in voltage e.g. between the collector region C2 and the emitter region E, the current from the emitter region 15 flows to the region 18 lower than the potential of the collector region 17 and does not flow to the substrate 11 side.

Title: Agc circuit
Inventor: TAKAHASHI YASUFUMI
IPC: H03G3/20
Filed: 1989-02-03
Abstract: PURPOSE:To prevent the saturation of a digital/analog converter (A/D converter) due to an adjacent signal occurring by providing an automatic gain control circuits(AGC circuit) at the front and rear stages of the A/D converter. CONSTITUTION:A signal outputted from a signal input terminal 1 via a band- pass filter(BPF) 3 is set at a constant level at the AGC circuit 4, and is converted to a digital signal at an A/D conversion circuit 5. Only a targeted signal is extracted from the signal by a BPF 6, and the signal of constant level is outputted from a signal output terminal 2 by the AGC circuit 7. Since the frequency band area of the BPF 3 is set wider than that of the targeted signal to suppress deterioration in the amplitude and phase of the targeted signal, the output of the BPF 3 includes the adjacent signal. However, since the output of the AGC circuit is kept constant at a global level, no saturation of the A/D converter 5 occurs even when the adjacent signal is inputted.

Title: Ignition timing control device of internal combustion engine for vehicle
Inventor: TAKAOKA ATSUSHI
IPC: F02D45/00
Filed: 1994-02-23
Abstract: PURPOSE:To prevent the occurrence of irregular combustion and knocking at the time of normal operations, and let a requisition for an output at the time of accelerating operations be met by letting a normal operating condition be judged based on a fact that internal combustion engine revolutions are kept on within a specified range of fluctuation for a specified period of time. CONSTITUTION:An internal combustion engine revolution is detected (step (S) 100). When the detected revolution of an internal combustion engine is kept on within a specified range of fluctuation for a specified period of time, it is judged that the internal combustion engine is in a normal operating condition (S110). When it is judged that the engine is in a normal operating condition, ignition timing for preventing irregular combustion and knocking is set up in the internal combustion engine (S120 through S140). Meanwhile, when it is judged that the engine is out of a normal operating condition, ignition timing for meeting an outputting requisition is set up in the internal combustion engine. By this constitution, either one of irregular combustion or knocking can be prevented, and delayed angle data can also be set up, so that both of performances for normal operations and accelerating/decelerating operations can thereby be enhanced.
